Abstract
The invention provides a method for producing a lightweight insulating brick by using agricultural production waste rice hull and corncob and forestry production waste saw dust as fuel and pore creating agent. The lightweight insulating brick prepared by the method not only has high strength and good insulating property, but also is energy-saving and environment-friendly, and has great economic value and social benefit.
Description
Technical field
The present invention relates to the light heat-insulating brick technology, particularly relate to a kind of adiabatic technology of changeing of biomass energy production lightweight of utilizing.
Technical background
Light heat-insulating brick iron and steel, cement, chemical industry, glass etc. industrial have widely use, be applied to, be applicable to the liner or the thermofin of petroleum cracking stove, metallurgical hotblast stove, ceramic roller kiln, tunnel furnace, electroceramics drawer kiln, glass pot kiln and various electric furnaces, and the furnace lining of blast furnace, the slide gate nozzle of concise steel, porous plug, lining brick and the liner of tower tray and aluminium cell, the guide rail of process furnace etc. of non-ferrous metal (copper, lead, zinc) smelting furnace, it can directly contact flame.
At present, the production of existing light heat-insulating brick is as basic fuel mostly with Sweet natural gas or coal gas, add polystyrene spheres as pore-forming material, these pore-forming materials can be burnt so that produce pore texture in the brick body in process of producing product, thereby reduce the density and the quality of brick body.
This production method is in process of production owing to need a large amount of fuel energies and the burning of polystyrene spheres pore-forming material will form a large amount of benzene series things, surrounding environment and atmosphere are produced harm greatly, and the polystyrene spheres cost is higher, burn aborning, also can cause the increase of cost and the waste of resource, not meet environmental requirement and Sustainable development policy that country advocates.
Therefore, how to solve produce a large amount of fuel consumption of light heat-insulating brick and produce in the pollution that surrounding environment and atmosphere are caused of the benzene series thing that produced of polystyrene spheres pore-forming material pore-creating, reduce resource and cost and raise, have extremely-huge economic and social benefit.
Summary of the invention
At shortcoming that exists in the prior art and problem, the object of the present invention is to provide a kind of replacement polystyrene spheres such as biomass energy sawdust, rice husk that utilize as pore-forming material and part Sweet natural gas, the method for coal gas equal energy source production light heat-insulating brick and the insulation brick that utilizes this method to produce.
Technical scheme of the present invention is as follows:
Utilize the method for producing light heat-insulating brick by biomass energy, may further comprise the steps, it is characterized in that:
(1) with the rice husk in the agriculture production, biological wastes such as sawdust in the production of forestry through levigate, sieve into the biomass energy raw material that fineness is not more than 10mm.
The biomass energy raw material that (2) will grind adds water 50% to carry out old about 15 days.
(3) according to weight ratio powder-material mullite 3.8%, fireclay 42.7%, biomass energy etc. 53.5% are mixed, wherein fireclay carries out superfine pulverizing and handles, and adds water and stir into the mud shape;
(4) mud shape batch mixing is carried out old viscosity and the plasticity of ageing mixture to improve pug;
(5) after being made green compact and drying, burns till old pug;
(6) with the adobe of burning till through cold-formed.
Described biomass energy can be a production of forestry refuse sawdust, also can be the rice husk that produces of agriculture production, corn cob etc., and its thermal value reaches about 5000 kilocalories.Can be used as fuel and also replace the light ball of polystyrene as pore-forming material.
Described green compact are prepared from by vacuum-extruder.
Described green compact burn till in tunnel furnace.
Described cold working grinds for adopting rattler.
A kind of light heat-insulating brick is characterized in that: described light heat-insulating brick is for adopting as previously mentioned
The light heat-insulating brick of method processing.
Technique effect of the present invention is as follows:
The present invention replaces part of fuel and polystyrene pore-forming material by utilizing forestry waste sawdust, agricultural wastes rice husk etc., mullite particle is done aggregate, do the matrix material with the fireclay of handling through superfine pulverizing, through processes such as batch mixing, ageing mixtures, after clay and water mixing, can make like this and produce good viscosity, with the good combination of mullite, clay and sawdust, made green compact are when burning till, its biomass energy will act as a fuel and pore-forming material will burn in process of production, produce the pore texture of uniformity in the brick body, obtain light heat-insulating brick.
Adopt biomass energy rice husk, sawdust, corn cob etc. both to act as a fuel in light heat-insulating brick, to act as a fuel among the present invention and burn till product, replace chemical pore-forming material polystyrene as pore-forming material again, has the good energy-conservation environment protecting, the main raw material mullite has characteristics such as volume density is little, thermal expansivity is little, thermal conductivity is low, the strength characteristics of product is able to remarkable enhancing, make the close characteristic of product body of light heat-insulating brick and product strength characteristic in conjunction with best.
Thisly utilize biomass energy to act as a fuel and the light heat-insulating brick of weighting material production is compared extremely as the lightweight of weighting material production with traditional polystyrene spheres: to have better effect of heat insulation, under identical adiabatic parameter condition, can be so that the obvious attenuation of kiln thickness, the volume size of kiln can be reduced on the one hand, the useful volume of kiln can be improved on the other hand; Hot compressive strength is higher, because its lightweight and low heat conductivity, the brick body is accumulated less heat, and energy-saving effect is more obvious in the periodical operation kiln; Prolong the work-ing life of kiln; Owing to do not re-use polystyrene spheres in the process of producing product as weighting material but use waste---sawdust instead as wood-processing industry, can effectively reduce product cost, economize on resources, reach the purpose of energy-conserving and environment-protective.
Embodiment
